for vertical slidable travel. The sash of the lower storm window isprovided with means to support a screen either in a position overlyingthe window or in a position elevated above the window. The lower stormwindow is also provided with means adapted to cooperate with a screendisposed below the window to support the window in the elevatedrelationship within the window opening.

A further object is to provide a window in such window and screenassembly which has a sash frame the top rail of which is provided with ascreen supporting channel extending therealong and projecting inwardly0f the inner face of the rail and the bottom rail of which window isalso provided with a screen supporting channel extending therealonng andprojecting inwardly of the inner face of the rail.

A meritorious feature is that the screen supporting channel that extendsalong the bottom rail of the window sash has a bottom wall that projectsinwardly and downwardly at an acute angle to the plane of the rail anddefines a space within which the top rail of a screen may be received tosupport the window in the elevated position and to maintain tightfitting engagement between the window and the screen.

A further object is to provide a screen for this window and screenassembly which is adapted to be supported by the lower window or tosupport the window and which is adapted to cooperate with the window toform close fitting engagement between the screen and the window. Thisscreen is provided with side rails which have flange portiOIls that formcontact below the window with the outer wall of the guide channel withinwhich the window is disposed for slidable movement. Such contact betweenthe flange portions of the side rails of the screen and the wall of theguide channel below the window is to provide a fiy-tight seal betweenthe screen and the window frame within which the screen is mounted belowthe window.

A further object is to provide a window with a metal sash the side railsof which are laterally adjustable to accommodate the window to windowopenings which vary slightly in size and which window sash includessupplemental top and bottom rails which are manually adjustable tomaintain the side rails at their laterally adjusted positions.

A meritorious feature of the metal guide channel within which thewindows are slidably mounted is that it has a plate associated therewithwhich is vertically adjustable to form tight fitting contact with thesill of the window frame within which the guide channel is mounted.

Other objects, advantages and meritorious features of the invention willmore fully appear from the following description, appended claims andaccompanying drawings, wherein:

Figure 13 is a fragment of the lower end of the guide channel withinwhich the window is supported for vertical slidable movement showing theguide channel adjustable plate.

The window and screen assembly here shown is illustrated as supportedwithin a window opening 3 in a building structure '20. This windowopening is shown as defined by a sill 22, a header 2%, and vertical jambpieces 26. This window opening is provided with the usual conventionalvertically slidable windows 28 and 30. The jamb 26 is provided with anouter stop 32, a parting stop 3d and a suitable inner stop 36 to guidethe windows 28 and 30 in their slidable movement. These windows form nopart or the invention.

The invention resides in the window and screen assembly which is hereshown as a storm window and screen assembly. It includes a pair ofcomplementary upright guide channels 38 formed of sheet metal andconnected at the top by a channel shaped header 48 forming an invertedU- shaped structure when disposed within the window opening. ThisU-shaped structureis disposed inverted within the window opening. Theheader member exhibits an upwardly open channel portion 42 which isreceived over the header stop within the window opening as shown inFigures 2 and 3.

The upright side guide channels 38 exhibit outwardly open channelportions 14 which are received over the stops 32 to secure the structurewithin the window opening. Each side member 38 exhibits-a pair ofinwardly open guide channels within which the two storm sash 46 and asare supported for vertical slidable movement. The upper and outer stormsash 46 is supported within the outer of these guide channels and thelower and inner storm sash 48 is supported within the inner of theseguide channels. The outer side wall of the inner guide channel, which isformed by a fold 5K3 in the sheet metal strip that is bent to form theguide channel upright frame piece, has a width greater than the innerside wall of the inner guide channel as will appear from Figure 4 for apurpose hereinafter set forth.

In order to accommodate this guide channel structure within windowopenings which may vary somewhat in vertical dimensions or wherein thesill may vary as to its angle a metal plate 52 is received within thefold 5!] and is vertically adjustable therein to form contact with thesill as shown in Figures 1 and 13.

The lower window 48 is provided, with a-metal sash which includesachannel shaped top rail 54 and a channel shaped bottom rail 56 each ofwhich extends along and embraces a margin of the glass pane. Asupplemental bottom rail memher is secured to the bottom rail '55 andexhibits an upwardly open channel portion 58 the bottom wall 60 of whichprojects inwardly and downwardly fromthe inner face of thebottom rail ofthe window at an acute angle as shown in Figures 2 and 3. This.supplemental bottom rail member has a channel portion 62 which embracesand extends along the bottom rail 56 of the sash 38 to secure the samethereto.

A supplemental top rail member is' secured to the top rail 54 of thesash. This supplemental top rail exhibits an upwardly open. channel 64and adownwardly open channel 66 which embraces the top rail 5d as shownin Figures 2 and 3. Each of these supplemental channel rail members issecured to its-sash rail in such a manner, asv to be adjustablelengthwise therealong and to frictionally retain its position ofadjustment thereover.

A side rail: Biiof channel shape embraces and extends along eachvertical side margin of the glass pane as shownv in Figures 11 and 12.Each side rail overlaps at the ends the top and bottom rails 5d and 55.The supplemental top and bottom rails heretofore described embrace thetop and bottom rails 54 and '56 between the two side rails 68. Each siderail 53 has a portion 10 extended over the end of the top rail or bottomrail so as to complete the frame.

Each side rail is adjustable laterally with re-' spect to the top andbottom rails and with respect to the glass pane as shown in Figure 11.Each side rail may be withdrawn horizontally relative I to the top andbottom rails and the supplemental top and bottom rails may be shifted asshown in Figure 11 so as to hold a side rail at its adjusted position.Due to this adjustment of the side rails it is possible to accommodate awindow to the proper width of opening to form a tight fit within thewindow frame opening while permitting slidable' movement of the window.Such window frame openings differ somewhat in size and with a woodensash it is customary to cut them to fit at the time of installation.This meta1 sash may be adjusted as above described at the time of itsinstallation.

As seen in Figures 1, 2 and 3, a screen which is indicated as, a unit as12 isadapted to be sup,- ported within the channel fi l of thesupplemental top rail member to extend above the window 481 This screenmay be positioned underneath the bottom walltiiof the channel 50 of thesupplemental bottom rail: member as shown in Figure 2 to support thewindow in the elevated relation ship. When the screen 72. has its bottomrail seated within the channel 64 of the top rail of the lower window asshown in Figure 3 the lower window may be raised until the top edge ofthe screen contacts the window header frame piece which will limit theelevation of. the lower window beyond a small distance sufficient forventilation but insufficient for unauthorized entrance.

When the screen unit is positioned with its top rail abutting the bottomwall 69 of the chan nel 'of the bottom rail of the window 48 it servesto support the window in the elevated position as shown in Figure 2 andpermits full ventilation through the lower half of the window frame. Theprojection of the bottom wall 60 of the channel 58 at anacute angle tothe bottom rail of the window forms tight fitting contact with the toprail of the screen and holds the same snugly against rattle andconstitutes a fly-tight seal.

The screen itself may be of the form shown in Figures 6 through 10'ofthis application. The screen illustrated in Figures 6 through 10comprises a sash frame having a top rail 14, bottom rail 16 andcomplementary side rails 18 secured together at their corners to form arectangular frame. with screen wire mesh stretched across the opening inthe frame and secured thereto. Each sash rail has its inner margin bentoutwardlyupon itself forming a flange sz-whichextends outwardly awayvfrom the margin at an acute angle to the plane-of the rail as shown inFigures sand- 9. The screen wire 86 is folded over this flange andachannel strip 84 is received over the fold in thewire. and over the edgeof the flange and. extends therealong all as shown in Figures 6 through10. These channel strips not only secure the screen wire :mesh inplacebut stretch it taut across the opening. and hold. it stretchedvthereacross. One side wall of each channel strip 84 is. folded-over atthe cor ner as at 86 (Figure 10) over its cooperating channel striptoformv a continuous retainer about theopening inthesash.

The screensash ishereshOWn as having each side rail provided at bothends with an extension 88. One of these end extensions folds over thetop rail 14 and theother end extension folds over the bottom rail 16 asshown in Figures 6, -7 and to secure the ends of the rails together toform'the rectangular sash. Each side rail 18 is so shaped by beingfolded upon itself as to exhibit a flange 90 which extends normal to theplane of the screen and away from the rail on the side opposite theflange 82 as shown in Fig. ures 2, 3, 8, 9 and 10. This flange 9% has awidth equal to the width of the inner guide channel within which thelower window 46 is adapted to travel so that when the screen issupported either above the lower window'or below such window the flanges90 extend across thischannel and engage the outer wall of the channel asshown in Figure 4 forming a fly tight fit therewith. These flanges 90are of such a length as to terminate short of the bottom margin of thebottom rail '56 of the screen as shown in Figure 3 so that when thebottom rail 16 is seated within the channel 64'. as shown in Figure 3the flanges 90 extend across the top rail of the lower window 48. Whenthe screen is placed below the window to hold it in the elevatedposition as shown in Figure 2 it is inverted, that is thc'rail 16 isusedat the top and the flanges 98 extend underneath the window as shown inFigure 2.

The screen may be used to hold the inner window in the elevated positionas shown in Figure 2 or the screen may be placed in an out-of-thewayposition above the lower window as shown in Figure 3. In Figure 3 theupper window 46 might be lowered if ventilation was desired through theupper half of the window or the screen might be disposed as here shownfor outof-the-way disposition as in the winter time when both storm sashare in use. Obviousl if desired the screen might be supported within thechannel 58 and the lower window partly elevated or completely elevatedin which the position the screen would not be in use.

This particular assembly is capable of being readily installed within awindow opening and of being left permanently in place and is adapted toserve the demands of .both winter and summer use. It represents anattactive, neat appearance and is of such a compact construction that itis receivable within a relatively small space so as to fit anconventional window opening.
